Merge bodice and trouser patterns leaving a space between them (= vertical wearing ease to be able to sit and walk comfortably):
- take back trouser, extend crotch line upwards and measure 5 to 7cm from center back above it. Place back bodice on the point you just found and make sure its side ends 3 to 5cm above trouser side seam
- then take front trouser, extend crotch line upwards (line should be parallel to grainline, while it was slanted on back – it is correct) and place front bodice in a way that space between bodice waistline and trouser waistline matches to back measurement. You’ll get a different distance in center front, it is right – just make sure center front bodice is on grain.
